Product Description:
This NFC-programmable OTP hardware token combines security, durability, and flexibility in a compact keyfob design. Equipped with a 6-character LCD screen and built-in button, it offers real-time display of one-time passwords (OTPs) based on the TOTP algorithm. Users can program the device via NFC using our free cross-platform applications. It's ideal for systems that require strong two-factor authentication (2FA), especially in environments where mobile apps or USB tokens are impractical.

⚠ Security Notice:
This device allows unrestricted time configuration without resetting the OTP seed. While this feature provides flexibility for non-standard systems, it also introduces a replay attack risk if misused. We strongly recommend using this token only with platforms that are not RFC-compliant (such as Cisco Duo). Contact us if you need assistance or are unsure whether your target system is compatible.Related products
